Product details

Product information

    This energy efficient LED MR16 spotlight light bulb is a high-quality, professional replacement for outdated 35W halogen spotlights, offering the same brightness, but using only a fraction of the energy. It is perfect for those wishing to upgrade to LED light bulbs while ensuring that the new light bulbs will not look out of place with existing fittings.

    The light bulb emits a bright 350 lumens of cool white light (4000K), with a narrow 36° beam angle that's perfect for highlighting products in retail displays, or in galleries and other display lighting. It is also dimmable, giving you even more control over your lighting.

    The light bulb's long 25,000 hour lifespan means that once installed, it will not need replacing again for years. The GU5.3 base also retrofits to existing light fixtures, so installing it is simply a case of swapping out the old light bulb for the new. As this is a low voltage light bulb, it will need to be fitted with a compatible driver or transformer when installed on mains circuits. See the manufacturer's website for more information.

    This LED MR16 spotlight lamp is fitted with a low voltage 12V GU5.3 2-pin (5.33mm apart) base.

    Please note that this light bulb will operate with most AC and DC 12V transformers. However, some 12V transformers may have a minimum required load which may not be met when installing low powered LEDs: these drivers may cause flickering or the LEDs not to function correctly. If this issue arises it may be necessary to source a suitable LED driver.
